Canon 5D Mark lll, Lightroom 4 Shadow Detail at 100%


Following yesterday’s post on 5D Mark lll shadow detail I’ve had numerous requests for a pair of shadow detail images, one of the full shot, the other of a 100% detail from the same image. The image below was shot in direct sunlight, with deep shadows in the seaweed, and highlights in the barnacles for a broad dynamic range in the image. (For the geeks, this was shot at ISO 100,  f/11, 100th of a second, at 65mm with a Canon 24-105 f/4L IS USM lens). Here’s a jpg reduction of the full image, cropped in height for the subject, but the full width (minor direction) of the original file:

Below is a crop from the center of the image, at 100%, so its showing the individual pixels, with minimal jpg compression in this version of the image. The image was opened into Lightroom 4.1. Three adjustments were made, all of them lens-specific. A sharp prime lens would probably require less, if any, adjustment for all three of these controls. They  were: an increase to Shadows, and increase to Clarity, and an increase to Saturation. Your mileage (and lenses) may vary. Please click on the detail below for a 100% view.

Canon 5D Mark lll, Lightroom 4 Shadow Detail


The shot below was taken the day after Easter, with the Canon 5D Mark lll. Two things we are always looking for from a new camera is more resolution, and more dynamic range. In this case the shot was time-sensitive, so switching to the 70-200mm lens which was in the camera case in the back of the car would have cost me the shot. Instead I stepped out of the car door, to remove the windshield from the photo, zoomed the current lens (24-105mm) to its longest throw, and shot just in time to capture this frame, before the crow flew away with his prize Easter egg.

So the question is: what would have been more useful here, more resolution, so that I’d have more pixels in this heavy crop, or more dynamic range, which allowed me to open up the shadows to bring definition to the crow? For those of you not yet reading between the lines, I’m asking if Canon’s choice in the 5D Mark lll in favor or not increasing resolution, and using that capacity to improve dynamic range instead, offered more to this shot; or if I would have been better off with Nikon’s new 800d, which would have produced half again as many pixels, but without an equivalent boost to the dynamic range.

Given the amount of character the detail in the feathers, and especially the eye, provide to the image, I’m not sorry it was the 5D used. And credit is due to Lightroom 4.1 as well, since the ability to bring out such shadow detail without undue noise and artifacts is something that previous versions of Lightroom could not have managed.

Another factor I should note is autofocus: I have used all my previous DSLR cameras almost exclusively in manual focus mode. The 5D Mark lll has such amazing autofocus I find I am using it more and more. Here, the time to manually focus was lacking, and it was only the fact that the camera was already in autofocus mode that saved the day. Picking the crow, tiny in the original image, out from the array of other highly detailed elements in the center of the frame was little short of amazing.
